T0 @ZZ whom t may concern.-

Beit known that we, ROBERT A. KINKELE and CHARLES L. Woman citizens of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Fireproof Floors, of which the following is a specification.

This invention relates to a iireproof floor, especially that of the dat-arched type, and the object of the same is to furnish a substantial and durable and yet a comparatively light floor; and the invention consists of 'a reproof floor comprising a series of supporting-blocks or tiles of inverted-T shape in cross-section, the side edges of the bases of said blocks being arranged so as to abut, while the central webs of said blocks provide spaces which are filled in with filling blocks or tiles of suitable cross-section, as hereinafter set forth.

In the accompanying drawings, Figure l is a transverse section of a iireproof iioor constructed in accordance with our invention. Fig. 2 is a modied form thereof, also in transverse section. Fig. 3 is another moditied formV in transverse section. Fig. 4. is an isometricalview showing portions of two I- beams and a View of the blocks supported between the same, while the dotted lines show the ends of the blocks.

Similar letters of reference indicate corresponding parts. i

The members of our improved fireproof floor are preferably supported on the flanges a of the usual I-beams or angle-irons A. The floor consists, in the main, of a number of blocks or tiles B, which are of inverted-T shape in cross-section and the bases b of which abut. The upwardly-extending webs b', formed by the stems of the Ts, provide between them suitable spaces, which may be iilled in with ashes, concrete, or any other suitable material, as shown in Fig. 4, or the spaces may receive filling-blocks O, as shown in Fig. l, said iilling-blocks containing, as shown in said figure, either a numberof bores or holes or a large chamber. The construction shown in Fig. et is for a cheaper class of work, while that shown in Fig. 1 is for a more substantial and durable floor.

In Fig. 2 the spaces between the webs h of the T-shaped supporting-blocks receive fill*- ing-blocks O which are of T shape in crosssection and the edges of the top portions of which are beveled or inclined, so as to iit cor` responding bevels formed at the upper edges of the webs of thc supporting-blocks, whereby an accurate and nice fit of the filling-blocks in the spaces between the webs of the supporting-blocks is obtained and the rillingblocks thereby iirmly held in position without danger of displacement.

In Fig. 3 the webs h of the supportingblocks are shown as beveled at opposite sides of their upper edges, as in Fig. 2; but the spaces between the webs receive slabs O2, the edges of which are beveled off, so as to correspond with the bevells of the webs.

In puttingin a iireproof oor in accordance with our invention it is rst necessary to place the supporting-blocks between the I- beams A, they being lowered by the workmen between the same and then turned transversely to such an extent that the end recesses b2, which are formed in the ends of the supporting-blocks, will receive the iianges a of the I-beams. The length of the supportingblocks with reference to the spaces between the I-beams is such that when they are placed in position they will be arranged at a slight obtuse angle, as shown clearly in the isometrical view, Fig. 4. i

The principle of the invention is the same in all of the forms shown, and it is evident that a builder may have his choice as to whether he desires a more costly or less costly construction, all of the constructions being quite durable and containing the gist of the invention, which lies in a series of supporting-blocks of inverted-T shape in crosssection, and the side edges of the bases of which, that are formed by the flanges of the Ts, abut, so that filling-blocks or tiles of suitable cross-section can be arranged in the spaces between the webs of the supportingblocks. The under surfaces of the bases of the supporting-blocks may furnish the ceiling, or plastering material may be applied thereto, .so as to impart a finish, the flooring being laid in the usual manner upon the upper part of the fireproof floor.

IOO

ranged in the spaces between the webs of the supporting-blocks and being of T shape in cross-section, the lower edges of the webs of said filling-blocks resting upon the abutting edges of the supporting-blocks, substantially as set forth.

In testimony that we elaiin the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
